|June 1, 1993
Summary
This study generalizes internal migration models beyond uniform flow, analyzing increasing or decreasing migration rates. It provides methods for estimating migration and predicting population, with an application to Dhaka.
Area of Science:
- Demography
- Population Studies
- Mathematical Modeling
Background:
- Traditional internal migration models often assume a uniform flow, which may not reflect real-world population dynamics.
- Rahman's (1987) work established a baseline for internal migration analysis.
- Understanding migration patterns is crucial for accurate population prediction and resource allocation.
Purpose of the Study:
- To generalize the assumption of uniform internal migration flow to scenarios with increasing or decreasing migration rates.
- To analyze migration rates proportional to national or regional populations.
- To develop procedures for estimating migration rates, pure migration, and population prediction.
Main Methods:
- Generalization of the uniform flow assumption in migration modeling.
- Analysis of migration rate proportionality to national and regional populations.
- Development of estimation procedures for migration parameters and population forecasting.
- Application using Census data for demographic analysis.
Main Results:
- A generalized framework for internal migration modeling accommodating non-uniform flows.
- Specific analyses for migration rates dependent on national or regional population sizes.
- Established procedures for calculating migration rates and pure migration.
- A population prediction formula derived from the generalized model.
Conclusions:
- The generalized model provides a more realistic approach to internal migration analysis than uniform flow assumptions.
- The developed methods are applicable for estimating migration dynamics and forecasting population trends.
- The study offers valuable tools for demographic research and policy planning, demonstrated by the Dhaka case study.

00:57Population Growth
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.However, realistic environmental conditions limit the number of...
01:29Exponential Growth
Bacterial populations exhibit exponential growth when conditions such as nutrient availability and temperature are favorable. In this phase, cells reproduce through binary fission, where each cell divides into two identical daughter cells. This process causes the population to double at regular intervals, resulting in a growth rate that is directly proportional to the current number of cells. As the population increases, the number of new cells formed during each generation also grows, creating...
01:27Growth Models with Integration: Problem Solving
In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...
01:26Exponential Equations for Modeling Growth
Exponential models are essential for describing rapid, multiplicative changes in natural systems, such as population growth. When a population doubles at regular intervals, the process can be modeled using a suitable base. For instance, a bacterial culture that doubles every three hours follows the model n(t)=n0⋅2t/3, where n(t) is the population at the time t.A more general model uses the natural base e, especially for continuous growth. This takes the form n(t)=n0⋅ert, where r is the relative...

Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...
01:25Modeling with Differential Equations
Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...
